[New Age] 'Mainstream' is definitely the word for this flourishing category

After years on the fringes, New Age—which includes some alternative health, addiction and recovery, psychology and spiritual titles, as well as books on Eastern traditions—may finally be approaching the middle of the road. Today yoga centers dot cities and towns throughout the country, and subjects like reincarnation and afterlife turn up on many television and radio shows. Even the New York Times bestsellers list reflects New Age themes, not just J.K. Rowling's Harry Potter titles, but Dan Brown's The Da Vinci Code (Doubleday), which is based on research into early religions, and Alice Sebold's The Lovely Bones (Little, Brown), which is narrated from the beyond.
